Write Below code in your Process Form Request immediately after super.processFormRequest(pageContext,webBean);

****************************************************************
if("oaAddAttachment".equals(pageContext.getParameter(event)) ||
"oaUpdateAttachment".equals(pageContext.getParameter(event)) ||
"oaDeleteAttachment".equals(pageContext.getParameter(event)) ||
"oaViewAttachment".equals(pageContext.getParameter(event)) )
{
System.out.Println("Attachement Event Raised");
pageContext.putSessionValue("returnAttachmentFlag","Y");
} //If-> Attachment Event
****************************************************************

Write Following code in your processRequest():

****************************************************************
String returnAttachmentFlag = (String)pageContext.getSessionValue("returnAttachmentFlag");
if(returnAttachmentFlag!= null && returnAttachmentFlag.equals("Y"))
{
//Do not execute Your VOs
System.out.println("Page Refresh after Attachement Event hence not executing VOs");
}

else
{
//Execute VOs
vo.executeQuery();
}
pageContext.putSessionValue("returnAttachmentFlag","N");
